BALL-RETAINER.

United States patent to Henry B. Keiper No. '686,617, granted November 12, 1901, and has for its object the productionoftasimple, efficientand inexpensive ball -re taining and separating device of the character referred to, which shall possess all of the advantages of the Keiper retainer, while easier and less expensive to make, being dis- .t-ing'uished therefrom by the peculiar construotion of the base-ring having ball-seat- ,ing furrows therein which extend trans versely of the axis of the ring and widen toward one edge, while the free ends of the standards overhang the ridges of the corrugati-ons. The Keiper retainer of the form shown in said Patent-N0. 686,617 is produced by cutting from sheet-metal a circular disk or plate, then drawing out the central portion of the disk so as to form a substantially hat-shaped body, then cutting out the top of the crown, and then cutting and bending the remaining portion of the blank so as to form a series of standards rising from the inner edge of a circular base, the free ends of the standards overhanging the base and being so formed that suitable spaces are provided for receiving balls which are confined in said spaces with out preventingfree rotation of the balls. This method .of producing the Keiper retaine'r results from the fact that there is not metal. enough'in the center of the circular disk or plate from which to form the series w ofstandards of the requisite length and width to perform the desired,functions.

My improved ball retainer and separator can be produced from a circular disk or plate ofsheet-metal, without drawing out the center of the disk and it has all of the advantages of the Keiper retainer while less 'expensi-veand easierto make.

Specification of Letters Patent.

then pointed out in the claims at the end of the description.

Figure l of said drawings represents a perspective view of a ball retainer embodying my invention; Fig. 2 is a transverse section of the same; Fig. 3 is an end view thereof; Fig.4 is a top or plan view of the device when arranged in a horizontal positionwith the standards uppermost, and "Fig. 5 is a similar'view showing the opposite side. Referring to said drawings, in which'the same reference letters are used to denote corresponding parts in different views, the letter denotes a ball retainer for ball bearings having a ring-shaped portion or base which is corrugated or formed with alternating ridges and depressions or furrows, the latter being denoted by the letter a and approximately semi-funnel-shap'ed, so that the surfaces. of the furrows extendtransversely and obliquely to the axis of the ring from the outer t0 the inner edge, the inner ends of the furrows being deeper and nar rower than the outer ends thereof. Projections or standards'B, B alternating with the furrows, rise from the inner edge or margin of the base substantially parallel with the axis of the ring and have their F NEW' furrows in the corrugated ring, and tobring the standards closer together than they were in the original blank, thereby forming suitable spaces between adjacent standards to receive and confine the balls without preventing free rotation of the balls.

The particular formation of the furrows and the standards hereinbefore set forth permits the balls to be snapped into place between the standards and seat in the furrows where they will be held out of contact and secured against displacement so that the retainer and the balls therein maybe inserted in or reinoved from a bearing with-- outloss of any balls or disturbing their relative arrangement.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

bearings consisting of a base-ring with spaced standards from one of its edges, the free ends of the standards 'overhanging said base-ring, the latter being corrugated, thereby providingba'll-seating depressions between the standards, said de-v pressions extending transversely of the axis of the ringand widening toward one edge of the ring and in effect increasing the length of the standards and lessening the distance therebetween.

3. As. a new article-of manufacture, a ball retainer and separator fonball-bearings consisting of a base-ring with spaced standards rising providing depressions between the bases of from its inner edge, the free endsof said standards overhanging. said -base, the latter being .corrugated,jthereby the standards to form alternating" ridges and ball-seating furrows which extend transversely of the axis of the ring and lessen the distance between adjacent stand-,

ards.

4. A ball retainer and separator for ball bearings consisting of a base ring with spaced standards extending from the inner edge. thereof parallel with the axis of the same, the free ends of the standards overhanging the ring, said base-ring being corrugated, thereby providing depressions between the'standards to form furrows having their inner ends dee er and narrower than their outer ends, w ereby spaces are provided to receive and retain the balls.

5. A ball retainer and separator for ball bearings consisting of a base ring with spaced standards extending from one edge thereof, the free ends of the standards overhanging thering, said base-ring being cor rugated, thereby providing depressions between the standards to} form furrows having their ends adjacent the standards narrower and deeper than their opposite ends, where by spaces are the-balls.

In testimony whereof I ture, in presence of two witnesses.
